The Registry replaces most of the text-based. The Registry contains information that Windows continually references during operation, such as profiles for each user, the applications installed on the computer and the types of documents that each can create, property sheet settings for folders and application icons, what hardware exists on the system, and the ports that are being used. The Microsoft Computer Dictionary, Fifth Edition, defines the registry as:Ī central hierarchical database used in Windows 98, Windows CE, Windows NT, and Windows 2000 used to store information that is necessary to configure the system for one or more users, applications, and hardware devices.

In 64 bit OS that is where the correct key is found.
WHAT TYPE OF NUMBER DO YOU NEED TO REGISTER WINDOWS 7 CODE
This code was written for demonstration purposes and should be adapted accordingly.ĮDIT: Someone stated wrongly that the 圆4 code is useless. so here is my answer: You will need to add a reference to "Microsoft.Win32". I my humble opinion none of the answers satisfies the question is pretty straight forward asking for a way to read the MachineGuid from the registry. That will be lost when the drive goes bad, but that usually takes out your product as well. Just use Guid.NewGuid() once and store the value in a file. With the considerable advantage that you won't piss off your customer when he updates Windows on his machine. Last but not least, do consider that it is pretty easy to generate your own unique id that doesn't depend at all on Windows.
WHAT TYPE OF NUMBER DO YOU NEED TO REGISTER WINDOWS 7 LICENSE
To what degree that key is reliably random on different machines isn't that clear to me, let's just say that this value is a pretty attractive target for the kind of users that are not very interested in paying the license fee for your product either. Just keep in mind that you are not reading the same information when you use Win32_OperatingSystem.SerialNumber. Which allows you to pass RegistryView.Registry64, ensuring that you'll read the non-redirected keys.
WHAT TYPE OF NUMBER DO YOU NEED TO REGISTER WINDOWS 7 UPDATE
If you are really stuck with x86 mode, typically because you have a dependency on 32-bit native code that you can't update then the next workaround is to use the. Your program itself however works "better" if you have the setting at An圜PU, including not getting bitten by the file system and registry redirection appcompat features built into Windows. And the Edit + Continue feature only works for 32-bit code. Which has a few limitations like not supported mixed-mode debugging. Particularly when debugging, VS is a 32-bit process itself so requires the remote debugger if your program executes in 64-bit mode. Microsoft prefers x86, Visual Studio works better with 32-bit mode processes. The x86 selection is the default for VS2010 and up, previously An圜PU was the default. Your program is actually reading the value of HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Cryptography\MachineGuid. Which has a number of side effects, the one that matters here is that access to registry keys are redirected. This setting forces your program to run in 32-bit mode on a 64-bit version of Windows. On VS2012, the "Prefer 32-bit" checkbox matters. Project + Properties, Build tab, Platform target combobox. This problem is caused by the platform target selection for your EXE project. Which is probably why it doesn't work reliably among different versions of Windows
